The International Teaching Assistants Interest Section (ITAIS) was established to serve TESOL members who are interested in a range of issues associated with non-native English speaking teaching assistants. These issues include, but are not restricted to, design of courses and testing programs, materials and test design and selection, the nature of and standards for spoken English discourse, and the culture of classroom communication in North America.

The ITA-IS seeks to encourage the sharing of expertise and specialized knowledge among ITA practitioners, to promote research into the spoken discourse of ITAs and the nature of classroom communication, and to foster communication between researchers and practitioners.
